Study of strength and hardness of plastic waste from polypropylene and low-density polyethylene for speedbump material
Year: 2024
Type: article
Abstract: The increase in human population causes the demand for food to always increase, as well as the increase in plastic that is no longer used and becomes waste that is just thrown away. Plastic waste is classified as waste that is difficult to decompose but can be recycled, one of which is by becoming the basic material for making speed bumps. Polypropylene (PP) and Low-Density Polyethylene (LDPE) plastics which will be recycled as speed bump materials. PP has strong properties and LDPE has elastic properties. The combination of a mixture of PP and LDPE has the potential to produce properties that are in accordance with the characteristics of the speed bump needs. The research method used was experimental. The stages of research activities were preliminary studies, preparation of material samples, material testing, analysis and conclusions. The research variable used was the test carried out by comparing the mixture of PP and LDPE compositions. Material testing carried out is a tensile and hardness test. The results obtained were the best composition of 80% PP and 20% LDPE with a tensile strength value of 7 N/mm2 and a hardness of 62 Shore-D.
